Abstract

Matière pour la fabrication par couches de corps tridimensionnels par frittage laser à l'aide d'une composition liante. Le corps fritté par couche à l'aide d'un faisceau laser est constitué de plusieurs couches formées par application de matière par passage à l'aide d'un dispositif de guidage préprogrammé et est fabriqué poreux. Les pores sont ensuite bouchés à l'aide d'une substance d'infiltration. Les substances de départ de la matière sont des constituants pulvérulents, à savoir une substance dure en tant que matière de base et une composition liante constituée d'au moins deux constituants liants, l'un des constituants liants se présentant sous forme d'alliage coulant. Les pores présents dans le corps tridimensionnel fini sont infiltrés à l'aide d'un métal d'apport de brasage fort à point de fusion élevé.
